Interesting app

I was able to see my brothers plane as it left Cancun and follow it to San Francisco. Then flight switch and followed him to landing back home in Montreal. It was like sitting next to him on plane. What I havent figured out are alerts. They come in as text messages on my iPhone without flight number and not listed in Alert History, so never know what plane it is.

Glaro about Flightradar24 - Flight Tracker, v6.7.0
